Consider the reaction below.
hi + h2o -> h3o+ + i–
which is an acid-conjugate base pair?
a. hi and h2o
b. h2o and h3o+
c. h3o+ and i–
d. hi and i–

and

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For the given chemical equation:

Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.

And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms which is a conjugate acid.

Hence, the correct answer is D.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
